The Knesset's Plesner committee is working on finding an alternative to the Tal Law, which exempts ultra-Orthodox students from the draft.

The Supreme Court declared the law unconstitutional. It is due to expire on 1 August.

"We must give our lives against the drafting of yeshiva students [to the army]," said Rabbi Shmuel Aurebach, one of the spiritual leaders of the Zionist Degel HaTorah political party. "In an issue that belongs to the heart of Israel, there are no compromises."

The demonstrators read verses from Psalms and performed prayers of lamentation in a public show of mourning.

National civilian service

According to the Tal Law, ultra-Orthodox men are excused military service for the purpose of religious study.

Some reports said that the committee will not recommend military conscription and may opt for drafting Haredi into a national civilian service, or fining those who refuse to be recruited.

"Instead of preparing the prisons for immigrants from Sudan, we suggest to those haters of religion to prepare 50,000 places of detention for yeshiva students who will refuse to be drafted," Pini Rosenberg, one of the speakers at the rally, said.

The Haredi are a small but active fringe ultra-Orthodox group that opposes the state of Israel.
